Hard mode of this Expedition, live on the global servers since the Oct 28 (CET) update. Same route and bosses as Conquest, with tighter rules and better rewards. Each boss below lists the Hard-only changes first, then the Conquest mechanics that still apply.
Item level 2,700 to enter. Every boss goes into Frenzy after 4 minutes, and each player can be revived only 3 times. NC has not said what Frenzy does — treat it as an enrage and plan to finish each boss inside the timer.

More Kina than Normal; Ariel Fragments for the new Ariel Daevanion board (the fragment type depends on the dungeon); a chance at Philosopher's Stone: Revelation, which you can also pick as the guaranteed reward; and a chance at Expedition Hero Artwork. Every Unique crafting material drops here, including Wrathful Mind, Wrathful Will and Wrathful Ego. In Substance Morph, 100 fragments become a Daevanion Crystal: Ariel (up to 30 per character) and 1 fragment becomes 5 Enhance Stones. Hard achievements give Unique skins.

The game sets no combat power requirement, and there are no global reports yet — the mode opened on Oct 28. The gate is 100 item levels above Krao Cave and Draupnir Hard, so bring a group that already clears those two comfortably. Stagger skills, buff food and scrolls matter on a 4-minute timer, and a Cleric with resurrection saves runs. Bosses in every Hard Expedition hit 10% softer since this update.

Boss 1 / 3
First boss
No Hard-only changes reported for this boss yet — its Conquest mechanics below still apply, now with the 4-minute Frenzy timer.
Same as Conquest
She retreats to the middle and poisons everything but a small circle around her; a flower blooms inside — kill it to clean the area. She throws poison at every player and it stays on the ground, so the whole group moves together in one direction to keep a clean patch.
Boss 2 / 3
Second boss — the boulder
No Hard-only changes reported for this boss yet — its Conquest mechanics below still apply, now with the 4-minute Frenzy timer.
Same as Conquest
Light circles flash under the players; stay in one and you turn to stone. The others break the stone fast, because a huge area hit comes right after and hits whoever is still trapped.
During the coloured buff, red means physical damage heals him; purple means magic damage heals him. Stop attacks of the matching damage type until that colour ends. This is about damage type, not melee versus ranged.

Boss 3 / 3
Final boss
He hits every player with four area attacks in a row, and each impact leaves a pool that keeps dealing damage. Lead them to the edge of the arena: pools in the middle make the red-rock phase much harder to get through.

He roots one random player in thorns and right away follows with a ring-shaped blast. The rooted player can't walk out, so stay close to him or well outside the ring when you can, and break the thorns fast.

Same as Conquest
He throws a seed at a player; a few seconds later it roots them in spikes with heavy damage over time and spreads to anyone close. The seeded player steps out of the group — not too far, so the others can still hit the spikes and free them.
The whole floor turns red. Three waves roll out from him — jump each one. At the same time attacks shoot out of the centre along lines in every direction, in two sets that take turns: stand between the lines of the next set. A moment after the third wave a blast covers the area: dodge it with a jump too. The easy way: on the third wave jump, press Space again and glide, and the blast passes under you.
He goes to the middle and pulls everyone in; rocks grow around him and one is reddish. The whole group breaks that rock and runs out of the circle through the gap — if it stays, everyone dies.
If hard-targeting keeps you locked on the boss, clear the target with Esc before selecting the red rock; avoid Tab immediately locking the boss again. Players also report Alt-clicking the rock. Check your combat mode and key bindings.
